Consider a Page Table with 32 bit virtual address size. Page size is 4 KB and the page table entry (PTE) size is 4 bytes a) If a system runs 8 applications, what is the Page Table size if the applications utilize 40% of the available memory. b) If the physical DRAM size is 12 GB, PTE of 4 bytes and the page table is single-level, how many PTEs are needed? c) How much physical memory is needed to store the Page Table
